With their comeback scheduled on Nov. 20, ASTRO members looked amazingly fierce in the music video teaser for Blue Flame.

In the video clip released by Fantagio Music, all of the six ASTRO members were shown in their individual settings, which were dominated by the color blue. The clip teased a portion of the lyrics and the hook choreography to further excite the fans for the comeback, All Kpop reported.

In the brief clip, ASTRO's JinJin, MJ, Cha Eun Woo, Moonbin, Rocky, and Sanha proved their striking visuals as they shifted from all-black clothing to coordinated black and white outfits which led to the strong aesthetic of the music video.

ASTRO's upcoming mini-album, Blue Flame, will be their sixth since their debut. The album will feature a total of five songs, including Blue Flame, When the Wind Blows, Go & Stop, All About You and You're My World.

Blue Flame is ASTRO's second comeback for 2019 after the group promoted their first full-length album, All Light, at the beginning of the year. After starting the year with their first music show win, Fantagio Music decided to end 2019 on a strong note for ASTRO and set the comeback date for November 20.

Unfortunately, the agency announced that ASTRO would temporarily be promoting as a five-member team for Blue Flame because of Moonbin's health issues.

Fantagio Music earlier stated that Moonbin will not be joining his members for Blue Flame's promotional activities after his doctors recommended that he take a break to receive treatment.

Moonbin reportedly went to the hospital after feeling unwell last week. However, after doctors examined the ASTRO member, they recommended that he take a brief hiatus so he could focus on getting enough rest and treatment.

The agency assured that Moonbin was well taken care of by medical professionals. However, Fantagio Music did not set a specific time for the idol's return.

It was an eventful year for ASTRO members, especially for Cha Eun Woo and Moonbin, who both appeared in television dramas. Cha Eun Woo took on the lead male character for Rookie Historian Goo Hae Ryung while Moonbin played a supporting role for JTBC's At Eighteen.

It was also reported that Cha Eun Woo was being eyed by the author of webtoon, True Beauty, to appear in the drama adaptation expected next year. True Beauty author Yaongyi also picked BLACKPINK's Jisoo to play the lead character, Ju Gyung, according to Cosmopolitan.
